  • Page 18: Connecting A Communication Cable

    Communication between a PowerScout meter and a logger is established with a serial RS-485 adapter or an Ethernet connection. A serial connection (RS-485) is limited in speed while a parallel connection (Ethernet) is much faster. PowerScout meters are ordered from DENT Instruments based on the type of desired connection.

    Pulse output is used to generate pulses for external devices such as data loggers that can accept pulses but do not have BACnet or Modbus capability. The PowerScout 3 Plus can generate pulses based on accumulated value(s) such as system kWh, system kVARh, and system kVAh. When a pulse is generated by the meter, the orange LEDs will briefly flash, otherwise they will remain dark.
